Microbiology refers to the scientific study of microorganisms, such as viruses, fungi and bacteria. One of the subsets of microbiology is medical microbiology, which is focused on the prevention, diagnosis and treatment of various infectious diseases. It studies microbes for finding out their clinical applications to improve human health. Immunology is a branch of biology and medicine, which includes the study of immune systems in every organism. Protozoa, bacteria and viruses cause various diseases, such as tuberculosis, leishmaniasis, malaria and dengue fever. Medical microbiology and immunology are interlinked, as the microbes which cause disease, trigger an immune reaction and control the immune system during the infection. An integrated approach of medical microbiology and immunology is focused on understanding the response of the immune system towards the infection in the host organisms. This book elucidates the concepts and innovative models around prospective developments with respect to medical microbiology and immunology. It will serve as a valuable source of reference for graduate and post graduate students.
